Firebase / GCP Migration Specialist Needed for Small JavaScript App

We need help transferring a fairly small existing Firebase app from one GCP account to another. The app is written in JavaScript and includes a few server-side Firebase/GCP functions that also need to be migrated and verified. You will be provided with an instruction set for the migration process, so this is not a project that needs to be figured out from scratch. However, you must be able to troubleshoot any issues that arise and get the app fully working in the new account. You should be comfortable with: JavaScript Firebase Google Cloud Platform Firebase Functions / server-side functions Firebase project setup, permissions, config, hosting, and deployment Debugging deployment, config, permission, and runtime issues Scope of work: Review the provided migration instructions Transfer the Firebase app to the new GCP/Firebase account Migrate and redeploy the server-side functions Update and verify environment/config values Troubleshoot any issues that come up during the migration Test that the app works properly after migration Note any final account settings or cleanup steps required This is a relatively small app, so I’m looking for someone who has done Firebase/GCP work before and can handle the migration carefully, solve problems as they come up, and get it working without overcomplicating it.
